Most companies need help with their phone support. Parents want a safe way to let their kids to call relatives without sharing their increasingly-important mobile phone. And businesses have an insatiable appetite for better sales information or help hiring great developers. All of these problems are solved in the most recent contest from telephony-as-a-service provider (and ProgrammableWeb sponsor) Twilio. The company typically runs a weekly contest for its Twilio API, but gave devs twice as long for this mega-contest, which also produced five winners.

Google plans to deprecate versions 1 and 2 of the Google Play Developer API later this year and suggests developers adopt version 3 sooner rather than later. The Google Play Developer API lets developers automate in-app billing and app distribution via the Play Store. It's time to upgrade.
